In addition, because the starters are designed and built in the UK, they fully address the specific needs of UK users, and excellent availability is guaranteed

Standard products in the new Moeller Electric enclosed motor starter range include direct-on-line types with ratings from 4kW to 11kW, direct-on-line reversing types with ratings of 4kW and 5.5kW and star-delta types with ratings from 5.5kW to 15kW. The starters are available in 230V and 400V versions for use on 50Hz supplies.

The starters come complete with or without an isolator and are supplied fully wired, requiring only the addition of an overload relay – which mounts directly on the contactor – to be ready for immediate use.

Crydom (Solid State Relays) Solutions for Heating Industry

July 17, 2007

 clogo.jpg

Crydom Solid State Relays (SSRs) are widely used in the heating industry. By specifying the Random Turn-on versions, Crydom SSR’s can be used as proportional controllers for varying power to resistance type heaters. Applied in a more basic way, when used in conjunction with “on-off” style temperature controllers, Crydom SSRs can be used as a power cycling switch without concern for contact arcing, burning, or the resultant reduction of life expectancy.

Crydom SSR Ranges.jpg

With the wide range of SSR types available, Crydom relays can be selected and used to control Quartz lamp, ceramic, infrared, CalRod, cartridge, immersion, strip, and band type heaters among many others. In addition, SSR’s can control fuel valves, blower motors, damper motors, and serve as the interface between thermostats and their primary equipment.

The Crydom MCTC Series of micro-controlled SSR/temperature controllers can be used as a stand alone temperature controller where a compact, low cost solution is required. The MCTC eliminates the need for a separate controller and SSR assemblies, by combining both into one standard size SSR package.

New ABB Terminal Technology Eliminates Wiring Mistakes on MCBs

July 13, 2007

ABB2.jpg

ABB has launched a range of miniature circuit breakers (MCBs) aimed at OEMs, panelbuilders and the industrial sector. The System pro M compact® incorporates a number of new features designed to eliminate wiring connection errors.

A key feature is the positioning of the cabling terminal in front of the busbar connection terminal, making both terminals easier to access and see. By placing both terminal ports at the bottom of the MCB, connections can be made secure by using only one screw to fasten both the busbar connection and the electrical cabling into their respective terminals.

ABB has also introduced auxiliary contacts for the pro M compact® range, which can be added to the bottom of an MCB instead of the side. Saving up to 50% space in enclosures, this feature increases the number of auxiliary contacts which can be installed, expanding the number of remote monitoring options. Plug-in connectivity also makes the contacts simple to connect.

The pro M compact® MCBs also offer a reduced height compared to ABB’s previous range, saving around 2cm of space per MCB. This provides additional installation space for when space is at a premium.

ABB’s patented release system enables easy removal without the need for a screwdriver. Release connectors on the back of the devices allow them to be simply disconnected from the busbar after turning power off and disconnecting the wiring.

The pro M compact® range is suitable for use worldwide as the materials used to manufacture them exceed standards for both European regulations for RoHs and UL, the US directive for electrical components. The pro M compact® MCBs can be ordered ready for installation for both Europe and the US. A Europe-only version is also available.
